- [AL]
- [AL\(^{-1}\)]
- [MAL]
- [MALT\(^{-1}\)]
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
The expression \( \frac{B}{\mu_0} \) represents a quantity related to magnetic fields.
The dimensions of \( B \) (magnetic field) are [M T\(^{-2}\) A\(^{-1}\)], and the dimensions of permeability \( \mu_0 \) are [M L\(^{-1}\) T\(^{-2}\) A\(^{-2}\)].
Therefore, the dimensions of \( \frac{B}{\mu_0} \) are [M A L T\(^{-1}\)].
